Engineered with High-Precision Cold-Rolled Steel for Maximum Mechanical Deflection Resistance and Tool-Free Assembly.
Founded in 2015, Foshan Dinghui Intelligent Warehousing Technology Co., Ltd. has established itself as an elite global manufacturer of heavy-duty industrial storage racks, pallet racking systems, and automated warehouse solutions. Our infrastructure features a state-of-the-art manufacturing facility spanning over 38,000 square meters, utilizing automated roll-forming and high-performance electrostatic powder-coating technologies.
By leveraging 12 years of core industry experience and 8 years of global export proficiency, we yield an annual export volume exceeding $25 million USD. Our primary export corridors span North America, Europe, Southeast Asia, and the Middle East, sustained by a network of over 850 strategic supply chain partners.
How the evolution of automated intralogistics and micro-fulfillment is positioning the boltless butterfly connection as the industry standard.
The rapid growth of rapid-delivery hubs and decentralized micro-fulfillment warehouses has created a strong demand for modular, boltless shelving. The butterfly hole profile allows operations teams to configure, expand, and relocate shelving bays without tools, reducing setup times by up to 65% compared to traditional nut-and-bolt structures.
Butterfly hole shelving uses a tapered slot design. When load is applied to the beams, the butterfly connector is driven deeper into the upright's matching punch, securing the joint further. This design provides high structural rigidity and reduces lateral sway under dynamic warehouse loads.
Modern commercial warehousing requires long-lasting surface protection. By using electrostatic thermosetting powder coating over high-grade cold-rolled steel, the shelves resist scratches and impacts while preventing oxidation in temperature-controlled or high-humidity facilities.
ISO 9001 Certified Quality System
Our quality control procedures conform to ISO 9001 and CE standards. Supported by our 35-member QA/QC team, we conduct testing protocols on every production batch to verify safety and performance limits before dispatch.
Raw Material Tensile Testing: Verifies the yield strength and ultimate elongation of our steel coil feedstocks.
Structural Load-Bearing Simulation: Evaluates upright deflection limits under asymmetric and overloaded distribution profiles.
Powder Coating Adhesion Testing: Uses cross-hatch cuts and impact tests to verify finish adhesion, ensuring long-term rust prevention.
Weld Non-Destructive Inspection (NDI): Ultrasonic and dye penetrant testing are performed on load-bearing components and support braces to confirm weld integrity.
How we are preparing next-generation shelving systems for modern warehouses and automated environments.
Reducing structural weight by 15% while keeping the rated load capacity intact. This supports sustainability initiatives and lowers international freight emissions.
Deploying specialized antimicrobial, low-VOC powder coatings for pharmaceutical storage and cleanroom environments, preventing microbial colonization on metal surfaces.

High-density picking configurations featuring multi-level mezzanines and picking lanes built on butterfly hole upright frameworks. Engineered to optimize item access speeds and floor-space utilization.
Specialized temperature-resistant powder formulations designed to resist thermal shock down to -30°C. Protects against corrosion caused by condensation in sub-zero environments.
Heavy-duty, wide-span shelving configurations engineered to support heavy tooling, steel parts boxes, and sub-assembly storage. Built to withstand high dynamic impacts in industrial zones.
Technical guidance regarding butterfly hole storage structures, load capacities, and customization options.
The butterfly hole system uses a tapered, dual-angled design. When dynamic load is applied, the beam's connectors settle deeper into the wedge-shaped cutouts. This creates a secure, self-locking fit that resists rotation and reduces frame deflection under load.
Yes, the butterfly hole connection is entirely boltless. Shelves can be adjusted in increments (typically 50mm or 75mm depending on the profile) without tools, requiring only a rubber mallet to secure or release the beams.
Our light-duty ranges support 100 kg to 200 kg per shelf layer. Our medium-duty configurations support 200 kg to 500 kg per shelf layer under uniformly distributed load (UDL) conditions.
We apply a multi-stage pre-treatment wash process, followed by an electrostatic application of thermosetting powder coating, cured in a high-temperature tunnel. This finish meets salt spray resistance tests, preventing rust during maritime transport and in humid storage facilities.
